Tradition is, in a sense and if such a comparison were profitable, more conservative than heredity. There is in the content of tradition an invariability which could not exist if it were a dual composite, as is the constitution of the germ-plasm. Here we must recall certain essential qualities of the mores which we have hitherto viewed from another angle. Tradition always looks to the folkways as constituting the matter to be transmitted. But the folkways, after the concurrence in their practice has been established, come to include a judgment that they conduce to societal and, indeed, individual welfare. This is where they come to be properly called mores. They become the prosperity-policy of the group, and the young are reared up under their sway, looking to the older as the repositories of precedent and convention. But presently the older die, and in conformity with the ideas of the time, they become beings of a higher power toward whom the living owe duty, and whose will they do not wish to cross. The sanction of ghost-fear is thus extended to the mores, which, as the prosperity-policy of the group, have already taken on a stereotyped character. They thus become in an even higher degree "uniform, universal in a group, imperative, invariable. As time goes on, they become more and more arbitrary, positive, and imperative. If asked why they act in a certain way in certain cases, primitive people always answer that it is because they and their ancestors always have done so." Thus the transmission of the mores comes to be a process embodying the greatest conservatism and the least likelihood of change. This situation represents an adaption of society to life-conditions; it would seem that because of the rapidity of succession of variations there is need of an intensely conserving force (like ethnocentrism or religion) to preserve a certain balance and poise in the evolutionary movement. Transmission of the mores takes place through the agency of imitation or of inculcation; through one or the other according as the initiative is taken by the receiving or the giving party respectively. Inculcation includes education in its broadest sense; but since that term implies in general usage a certain, let us say protective, attitude taken by the educator (as toward the young), the broader and more colorless designation is chosen. Acculturation is the process by which one group or people learns from another, whether the culture or civilization be gotten by imitation or by inculcation. As there must be contact, acculturation is sometimes ascribed to "contagion." 4. Temperament, Tradition, and Nationality[78]
